IMPROVEMENT IN PUMPS.

Be it known that I, WILLIAM H. KEEP, of the city of Stockton,'ot` the county of San Joaquin, and State of California, have invented a new and useful Improvement in the Mode of Constructing and Securing the Valve- Ghambers and Valve'Seats of Pumps; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being, had to 'the accompanying drawings, forming a. part of this specification, in which i Figure 1 is a side elevation in perspective of a force-pump, with my improved valve-chamber attached.

Figure. 10, a vertical transverse section of valve-seats and valve for lift-pump. Similar letters of'reference indicate correspondingparts in all of the figures.

To enable those skilled in theart'to make vund use my invention, I will proceed to describe the lconstruction and operation of the same.

For .a force-pump, the cylinder or barrel A, gs.`1, 2, with plunger or piston, 35o., is constructed in any of the known forms. To this barrel 'or cylinder I attach, by anyY known method, my valvechamber B, figs. 1 and 3, having the suction-pipe D and discharge-pipe N attached.

On the inside' offthe chamber, at any point between the discharge-pipe N and the connection O between the chamber and barrel or cylinder, I form a. shoulder or ange, E, figs. 1 und 3. At the bottomof the chamber I form n. ange, C, figs. 1 and 3', either on' the inside of chamber or separately, and connect it to the chamber by bolts or otherwise.

The chamber also has a. bonnet orcover, L, figs. I, 2, and 3, on 'the top, secured by bolts or otherwise. The lower' or suction-valve seat F rests upon the flange-C, with or without packing, but so as to ferm a water-tight joint. Around the upper edge of valve-seat is a shoulder, which receives the ring G, gs. 3 and 4, which is connected by a skeleton-frame or b ars P, figs. 3, 4, and 6, to the upper valve-seat H, figs. 3 andglt. Around this I valve-scat, onthe outside, is a flange, K, gs. 3, 4, and 5, which forms a water-tightjoint on the shoulder E of valvechamber, thus compelling the water, when passing fromthe barrel or cylinder,to raise the discharge or upper valve beforeit can pass to the discharge-pipe'N. Around this valve-seat, and above the flange K, is a. ring, I, igs. 3'and 4, which is connected by a skeleton-frame or bars to the cross-bar J, figs. v3, 4,'and 5.

In the-bonnet or Acover L, I put a screw-bolt or set-screw, which, pressing upon Athe cross-bar J, secures-the valvesents in their position.' The valves are of any of the usual forms known as poppet-valves or clapper-valvcs.v

My mode of adjusting and securing the valveseats in the chamber is as foliows I place the valve-seat F upon the flange O,with rubber, leather, lead, or any other known packing between, so as. to forni a water-tightjoint.

4Ithen place the suction or lower va'lve in its position, and place the ring G upon the shoulder of the valveseat F, which will bring the .flange K to u bearing on the shoulder E, fig. 3, so as to form n water-tight joint. I then yplace the upper or discharge-valve in position, then place the ring I upon the flange K.

I then secure the -bonnet or cover L in its position, and insert the screw M, sc as to bear upon the crossbar .Land by forcing that down, I secure the valve-seats firmly in their place.

For a lift-pump, I construct my barrel or lcylinder' A, fig. l', with a piston or plunger containing a. valve, in any of ,the known' forms, and connect my valve-chamberv B, figs. 7 and 8, inthe sameman'ner as for a force-pump, I construct `my valvelchamber B, iig. 7, in anyof the known formswitl1' a ilange, C,'iig. 7, on.the inside,

or connected by-bolts or otherwise to th'e bottoni, and a bonnet or cover, L, iig. 7, at the top. The valve-seat vF, iig. 7, rests upon the flange C, with rubber, leather, or other known packing, so as to form a. water-tight joint. The upper edge 'of the valve-seat has a shoulder which receives the ring G, which is connected by the skeleton-frame or bars P with the cross-bar J.` The screw M passes through the bonnet or cover L, and, press. ing upon the cross-bar J, secures the. valve-seat in its position; or this water-tight joint maybe constructed as the upper joint in iig. 3, by shoulder E vand ange K.

Ihe valve-seats and skeleton-frames or bars for both force and lift-pump are made suficiently smaller than the inside of the chambers, so that they will not come in contact with the body of the saine.

It will be seen that by this peculiar method of constructing and securing the valve-,chambers and valveseats, the valve-seats or valves may be taken from the chambers, when necessary to do so for repairs or duplication, by simply removing the bonnet or cover, thus avoiding the necessity of breaking thejoints of either suction or discharge-pipe. Y

I do not claim the cylinder or barrel, nor the piston or plunger, nor the valves, for they are all well known,

`and have long been in use; but

What I doelaim as new, and desire to secure by Letters Patent, is- The bail J, in combination with the ring I, the valve-seat H, the frame P, the ring G, and the valve-seat F, as andvior the purpose set forth.
